| Recently there was a thread on soldering paladium leads on ICs. A gent from TI suggested an article he had written. Various folks suggested making sure the reflow profile peaked above 215C. | My question is: How does one recognize paladium leads

After reflow the paste on a copper pad should spread out from its original print dimensions it should ideally not prior to reflow as that is a hot slump. The better the solderability of the OSP or the higher the activity of the flux will greter flow

Sorry about the non SMT post, but I figured that there might be someone with a similar experience out there. We have been having a tough time cleaning the conveyor chains in our wave solder machine. We have been cleaning them in a self cleaning oven,

I will start with the statement that I think it is great that we have the ability to solder SMT components that emulates wave soldered components. With that in mind, I would want to find acceptance criteria to be similiar, regardless of the solder me

Again, I really appreciate the valuable input you all provided. Got my Air-Vac SRM4 machine Friday afternoon. Stored it safely in my cube over the week-end for safe keeping. Tried to find 220V single phase next to air with no luck yesterday. Electric

Michelle, Traditionally, the adhesive side is always run first since most designers put passives (resistors, caps) on the adhesive (solder side) of the board. I worked in an environment where we did the adhesive side first, sometimes the boards "sa

| We are having a small number (~2%) of our boards pass our manufacturing diagnostics, fail once they reach the customer, fail when they get back to us and then start working again after handling them for a short time. We have eliminated a lot of it

We are now using solder paste(OM325) and I have some problems on the folowing process: 1. We use the solder paste softer(Malcom SP-1) to warm-up for 20 mins, when it just take from refrigerator. Is there any problems for solderpaste performance? 2.

Customer returned a board and a 50 pin connector with .020" pitch that "fell off". after looking under a scope i can see the plating of the connector embedded in the solder. To me it looks like it broke off. Designer did not put the anchor pads on th

| There is a company selling pcb with the solder past on the pads and coated with a tacky film to hold the part during assembly. Have you heard of them and can you tell me how to contact them? | Contact Matt Kehoe at 770-475-4576 or 847-740-4120 T
